19-2327; Rev 2; 12/08 KIT ATION EVALU E L B AVAILA LVTTL/TTL/CMOS-to-Differential LVECL/ ECL Translators The MAX9360/MAX9361 are low-skew, single LVTTL/ TTL/CMOS-to-differential LVECL/ECL translators designed for high-speed signal and clock driver applications. For interfacing to LVTTL/TTL/CMOS input signals, these devices operate over a 3.0V to 5.5V supply range, allowing high-performance clock or data distribution. For interfacing to differential LVECL/ECL output signals, these devices operate from a -2.375V to -5.5V supply. The MAX9360 is a 3.3V LVTTL/CMOS-to-LVECL/ECL translator that operates at a typical speed of 3GHz. The MAX9361 is a 5V TTL/CMOS-to-LVECL/ECL translator that operates at a typical speed of 1.3GHz. Both devices can be used to drive either LVECL devices or standard ECL devices with a negative supply range of -2.375V to -5.5V. The devices default to high if the input is disconnected, and feature ultra-low propagation delay: 440ps for the MAX9360, 810ps for the MAX9361.

For interfacing to LVTTL/TTL/CMOS input signals, these devices operate over a 3.0V to 5.5V supply range, allowing high-performance clock or data distribution in systems with a nominal 3.3V or 5.0V supply. For interfacing to differential LVECL/ECL output signals, these devices operate from a -2.375V to -5.5V supply. The MAX9360 is a 3.3V LVTTL/CMOS-to-LVECL/ECL translator that operates at typical speeds of 3GHz. The MAX9361 is a 5V TTL/CMOS-to-LVECL/ECL translator that operates at typical speeds of 1.3GHz. Both devices can be used to drive either LVECL devices or standard ECL devices with a negative supply range of -2.375V to -5.5V. Input The MAX9360/MAX9361 inputs accept standard LVTTL/ TTL/CMOS levels. The input has pullup circuitry that drives the outputs to a differential high if the inputs are open. Differential Output Output levels are referenced to GND and are considered ECL or LVECL, depending on the level of the VEE supply. With GND connected to zero and VEE at -4.2V to -5.5V, the outputs are ECL. The outputs are LVECL when GND is connected to zero and VEE is at -2.375V to -3.8V. Traces Input and output trace characteristics affect the performance of the MAX9360/MAX9361. Connect each signal of a differential output to a 50 characteristic impedance trace. Minimize the number of vias to prevent impedance discontinuities. Reduce reflections by maintaining the 50 characteristic impedance through connectors and across cables. Reduce skew within a differential pair by matching the electrical length of the traces. On the MAX9360, if the input edge rate approaches the electrical length of the interconnect, then controlledimpedance transmission lines should be used for the input traces. Output Termination Terminate outputs through 50 to -2V or use an equivalent Thevenin termination. Terminate both outputs and use the same termination on each for the lowest outputto-output skew. When a single-ended signal is taken from a differential output, terminate both outputs. For example, if Q is used as a single-ended output, terminate both Q and Q. Ensure that the output currents do not exceed the continuous safe output current limit or surge output current limit as specified in the Absolute Maximum Ratings table. Under all operating conditions, the device's total thermal limits should be observed. Applications Information Chip Information Supply Bypassing Bypass VCC and VEE to ground with high-frequency surface-mount ceramic 0.1F and 0.01F capacitors in parallel as close as possible to the device, with the 0.01F value capacitor closest to the device.
